ResponsiveKite class

Lifecycle-safe responsive boundary.

Public usage remains unchanged:

builder: (context, child) {
  return ResponsiveKite(child: child!);
}

The first application frame intentionally exposes a compact responsive snapshot. On Flutter web debug this avoids eagerly mounting the much larger desktop tree while DDC is still lazily linking libraries. Immediately after that first frame, Kite promotes the scope to the real MediaQuery width.

Once bootstrapped, MediaQuery changes are applied normally and WidgetsBindingObserver.didChangeMetrics provides an extra web/desktop safety net.
